Clean lakes are an important water resource for many reasons. They are a great attraction for tourists, a place where many activities such as fishing, swimming and sailing can be enjoyed, and a natural environment for wildlife. They can also be used as reservoirs.

Crater Lake in Oregon is the deepest lake in North America. It is actually a caldera lake and was formed some 7,700 years ago by the collapse of the volcano that is known today as Mount Mazama.
With no rivers going in or out of the lake, it is only filled by rain and melted snow and there is little to cause water pollution. Because of this Crater Lake has become world famous for its exceptional clarity and deep blue colour.

Crater Lake is also famous for a full-sized tree that, preserved by the coldness of the water, has been bobbing about in the waters of the lake for over a century and has now worn down to a very large stump and has affectionately become known as the “Old Man of the Lake.”
